Normally the inking-roll is, held against the printing-roll by means of springs or elastic draft devices at I. In the drawings I have shown linksS interposed between the springs I and gudgeons of the printing-roll. I e

. I One of the objects of the present invention is to provide printing mechanisms of a character such that they can be made in large number each similar to the others and 'yet of paper of differingdiameters and widths Y and shall also be adapted to print uniformly placed in: relation to the axis of the roll of paper. This I' have accomplished principally the parts that the carrier which directly supwith the spring or bracing device, which tends to force the printing-roll against the paper. J- J indicate arms or bars which extend upward from the printing mechanism; They no matter atwhat' distance they may beby combining with, the printing mechanism have succeeded in simplifying and cheapening mechanisms of this sort by so arranging any desired lengthcan be torn or cut off by in a common support. As shown, thiss'uping wall or housing h. As shown, theprint- I 'ing-roll F is mounted upon a fixed axis in the.

be adapted for use in 1 connection with rolls ports the printing mechanism-shall be in one are fitted to the latter by means of tubes or sleeves at E, the latter carrying set-screws e or their equivalents for firmly fastening the printing device and the carriers J. The screws can be loosened at any time, and the parts for printing can be placed higher or lower, as may be desired, to attain the best results. As shown, these carriers .I are the downward-projecting parts of a spring-rod that is to say, the rod of which they are formed is atjj bent to form two coils, with a relatively straight central connecting-arm at j. This spring-carrier is not connected to the framework in the manner heretofore followed in making devices of this class, but in a way which I have been led to as a result of experience with those of the earlier sort. K indicates as a whole a main support for the printing mechanism. It is formed of aheavy rod or wire having the horizontal arms 70, bent to provide the legs 75, the joining-loop k and the eyes The loop 70 is primarily bent downward somewhat toward the parts It, so that it shall be capable of exerting a powerful grip upon the cross-bar B of the rollframe and can therefore be utilized as the entire means of detachably and adjustably fastening the printing mechanism.

The above-described spring-carrier J jj is detachably connected to this support K as follows: The connecting-rod j between the spring-coils j is laid'upon the top of the arms k, and the latter provide an abutment against which the spring acts in its work of forcing the printing roller against the paper. A removable shaft or mandrel L is inserted through the spring-coils j and through the eyes k of the top support and afterinsertion is fastened by means of cotter-pins or keys 1.

I am aware of the fact that it has been heretofore proposed to construct supports for such printing'mechanisms of one or more pieces of spring-wire extending continuously from the printing device to the frame-bar of the paper-roll, but have found serious difficulties to be incident to such construction. On the one hand, if the spring-wire is of a gage equal to that which I employ in making the holder at K the force is so great that the parts become practically inoperative and the friction is increased to such an extent that the paper is torn and marred in withdrawing it. On the other hand, if the entire support is made of spring-wire of a gage such as to bemerely sufficiently powerful for properly holding the printing-roller then the top part fastened to .the frame. is relatively so weak that it yields in an undesirable manner under the pressure and imperfect printing results. As pointed out above, the holderK is made of relatively large spring-wire, which is of relatively low flexibility, so as to provide a strong and suitably rigid support, while the carrier J is of lighter wire having a relatively high flexibility, so that the printing mechanism will be properly held against the roll until the latter is exhausted. By

forming these parts in the way describedthat is, with wire of one gage and tension and of relatively low flexibility for the top holder K and with wire of a lighter gage and tension and of a relatively high flexibility for immediate attachment to the printing device and joining them with a detachable hinged mandrel,as at LI overcome these difficulties and at the same time provide for the immediate fastening of the attachment to any of the ordinary counter paper-supports without requiring screws or bolts, I depending merely upon the powerful grip provided by the arms at 7c and the loop at 10 In case one of the spring-carriers .I j becomes broken, losing its elasticity, it is not necessary to abandon the entire holder, as another spring can be readily inserted by withdrawing the mandrel L and applying it in the way described.

Again, by examining Figs. 1 and 2 it will be seen that an attachment of the sort above described can be applied to the paper-supports commonly in use having three or more sections, I having succeed-ed in so relatively arranging the parts that but little room is required and so that each attachment can be used interchangeably with either of the rolls in the tier.

Each printing device can be placed at any point desired along the paper laterally, as the gripper at 70 70 while being powerful'enough to hold the parts in any position of adjustment, is such that it can at will be placed at one point or another transversely of the 'frame, there being, as above said, no screws or bolts required for the fastening.

What I claim is 1. In a printing attachment for paper-rolls, the combination with the frame which supports the paper-roll, of the spring-carrier, means for securing it to the roll-frame and the printing mechanism vertically adj ustably secured to the spring-carrier, substantially as set forth, wherebyit can be held in ahigher or lower position.

2. In a printing attachment for paper-rolls, the combination with the frame which supports the paper-roll, of the spring-carrier having downward-extending projections, means for securing the spring-carrier to the frame, the printing-roll, the inking-roll, and the holder for the rolls having guides for adjustably receiving the said downwardly-extending projections of the spring-carrier, substantially as set forth.

3. In a printing attachment for paper-rolls, the combination with the frame which supports the paper-roll, of the printing mechanism, the spring-carrier for the printing mechanism having the coils jj and'the abutment part 7 integral with and situated between the coils, the spring-gripper detachably fastened to the roll-frame and provided with eyes, and the rod or mandrel L passing through the spring-coils j and the said eyes, substantially as set forth.

between the carrier of the printing-frame and the holder secured to the roll-frame, whereby the carrier and the holder can move freely relatively to each other, substantially as set forth. V i
